MACHINE FOR CRIMPING PAPER CAR-TONS.

Specification of Letters Patent.

Patented Jan. 19, 1915.

Application filed November 9, 1912. Serial No. 730,509.

To all whom it may concern Be it known that I, GEORGE W BEADLE, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Machines for Crimping Paper Cartons; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to crimping ma, chines capable of being operated by hand, adapted to turn over or crimp in the edges of paper bottles or cartons, and has for its object toprovide a machine of this kind which will be simple in construction, efficient in action, rapid in operation, and comparatively inexpensive to construct.

lVith these and other objects in view, the invention consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claim.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views 1-- Figure 1 is a side elevational view partly in section ofa machine built in accordance with my invention; Fig. 2 is asectional view on the line 22 of Fig. 1;-Fig. 3 is a. top side view of the bottle support when removed from the machine; Fig. 4: shows a slightly modified form of crimping tool from that shown in Fig. 1; Fig. 5 is a sectional view of the form of crimping tool shownin Fig. 4; and, Fig. 6 is an elevational view partly in section of a paper bottle or carton after having been crimped on this machine.

1 indicates any suitable base on which,

is mounted the standard 2, to the upper end of which is attached the casting 3 provided with the bracket or holder 4 having the bead 5 adapted to enter the groove 6, with which my bottles are ordinarily provided. The casting 3 also carries the arm 7 through which passes the stud shaft 8, towhich is attached the crank arm 9 at one-end, and the crimping disk 10 at the other end.

The crimping disk 10 is provided with the crimping groove 11 adapted to receive the flange 12 of the bottle, and to..turn the same over or crimp it down upon the closing disk 13 of said bottle, in a manner Well known.

The lower end of the standard 2 is provided with the sliding sleeve 14, split as at 15, and having the tightening device 16 passing therethrough in order to firmly grip the said sleeve 14 to the standard 2. I

The sleeve 14 also has rigidly attached thereto the extending arm 17 perforated as at 18 to receive the stem 19, to. the upper -end ofwhich is attached the bottle support As is'well known, paper bottles or cartons, adapted for containing milk and other liquids, are paraflined inside and out, and when this paraflin coating is broken, or otherwise injured, the liquid readily passes through the same, softens the paper walls of the bottle, and collapses the entire package) It is, also well known that in order to provide a closure which is to be liquid tight, and one which is to be so firmly seated in the-bottle that the squeezing or compression.

of the bottle body will not unseat the same, it is necessary to locate said closure, such as 13, upon a seat, such as 6, and to turn over or crimp-in the edge 12 of the bottle so as to form the locking lip 26, as illustrated in Fig. 6. But, heretofore when it has been attempted to crimp in this edge 12, the bottle would turn in its supports, and injure the paraffin coating. That is to say, if the bottle is supported in clamps passing around its body portion, and if the clamps are set up sufficiently tight to prevent the bottle from turning, the walls thereof being pliable will be squeezed in, and thereby will force the contents up against the disk 13 and displace the said disk. The result is a bad closure. On the other hand. if the clamp is not set up sufliciently tight to involve this objection, then the bottle turns in the clamps, the paraffin coating is scraped off, and later when the bottle comes in contact with moisture due to the ice in which the'bottle may be packed, or due to other such as milk, is lost. Again, when the bottle is seated upon the usual smooth base and it is attempted to crimp in the upper edge as illustrated in F ig. 1, the bottle again rotates, and scrapes off the paraiiin with its attendant consequences, or else a bad joint is formed. These and other objections have rendered it heretofore impossible to provide a commercially successful hand crimping machine which would enable the dairyman to successfully close his own bottles, and thereupon get his milk to market. I have discovered, however, by the simple expedient of roughening the bottom support 20 of the bottle, as indicated at 21, that the edges 21 will sufiiciently bite into the thickened bottom portion of the bottle as to hold the same firmly without injuring the parafiin coating at all, and that an exceedingly efficient and inexpensive joint can be formed, such as that illustrated in Fig. 6, for example.

In order to facilitate the action, the hand lever 25 enables one to raise the bottle quickly into its crimping position after having placed the said bottle upon the support 20, and by feeling the pressure with one hand while crimping the bottle through the lever 9 with the other, the whole operation is very simple and effective. Bottles thus sealed are found to give eminent satisfaction in practice, and to fulfil all of the requirements. Further, if the stud 8 is removed from its support 7 along with the handle 9, and if the crimping disk 10 is then replaced upon the stud 8, the same may be placed upon the upper end of the bottle while the body is held in the hand and the closure 13 thereupon secured in place, even without the rest of the machine.

In Fig. 4 there is illustrated a modified form of crimping tool especially adapted for this purpose, wherein the crimping lugs 30 are formed outside of the annular rim 31, and each lug is provided with a groove 32 into which fits the rim of the bottle. Such a tool, when attached to the handle 9, can be-placed over the bottle mouth in a manner which will be clear from Fig. 1, and

while the bottle is held in the other hand,

of course, not with the same facility as it can be manipulated when .held in the machine, as illustrated in Fig. 1.

It will be observed that the problem here solved of closing parafiin coated paper bottles, is quite different from that encountered in the closing of glass milk bottles, and for the reason that when glass is employed, there is no danger of squeezing in the sides, nor of destroying the paraifin coating, and therefore, the rough edges 21 would be of no utility whatever in such cases.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of my inventlon, and therefore I do not wish to be limited to the above disclosure except as may be required by the claim.

What I claim is In a crimping machine for closing the mouths of bottles provided with grooves, the combination of a base member having a roughened surface on which the bottle rests; a support for said base member comprising a clamp; a standard adapted to be traversed by said clamp; a rack and pimon associated with said support adapted to readily raise and lower said base member; a circular member provided with a rib adapted to enter said groove and carried by said standard adapted to surround said bottle near its upper end when resting on said base member; a crimping member provided with a groove adapted to receive the extreme upper edge of said bottle and turn the same over; and means comprising a handle rigid with said-crimping member for readily rotating said crimping member,

substantially as described.

In testimony whereof, I affix my signature, in presence of two witnesses.
